Does Python have a package module management system

Question

Does Python have a package module management system  similar to how Ruby has rubygems where you can do gem install packagename   On Installing Python Modules  I only see references to python setup py install  but that requires you to find the package first

As of at least late 2014  Continuum Analytics  Anaconda Python distribution with the conda package manager should be considered  It solves most of the serious issues people run into with Python in general  managing different Python versions  updating Python versions  package management  virtual environments  Windows Mac compatibility  in one cohesive download   It enables you to do pretty much everything you could want to with Python without having to change the system at all  My next preferred solution is pip   virtualenv  but you either have to install virtualenv into your system Python  and your system Python may not be the version you want   or build from source  Anaconda makes this whole process the click of a button  as well as adding a bunch of other features

I don t see either MacPorts or Homebrew mentioned in other answers here  but since I do see them mentioned elsewhere on Stack  Overflow for related questions  I ll add my own US 0 02 that many folks seem to consider MacPorts as not only a package manager for packages in general  as of today they list 16311 packages ports  2931 matching  quot python quot   albeit only for Macs   but also as a decent  maybe better  package manager for Python packages modules  Question  quot    what is the method that Mac python developers use to manage their modules  quot  Answers   quot MacPorts is perfect for Python on the Mac  quot    quot The best way is to use MacPorts  quot    quot I prefer MacPorts    quot    quot With my MacPorts setup    quot    quot I use MacPorts to install     third-party modules tracked by MacPorts quot    SciPy  quot Macs  unlike Linux  don   t come with a package manager  but there are a couple of popular package managers you can install  Macports    quot  I m still debating on whether or not to use MacPorts myself  but at the moment I m leaning in that direction

Since no one has mentioned pipenv here  I would like to describe my views why everyone should use it for managing python packages   As  ColonelPanic mentioned there are several issues with the Python Package Index and with pip and virtualenv also   Pipenv solves most of the issues with pip and provides additional features also   Pipenv features  Pipenv is intended to replace pip and virtualenv  which means pipenv will automatically create a separate virtual environment for every project thus avoiding conflicts between different python versions package versions for different projects    Enables truly deterministic builds  while easily specifying only what you want  Generates and checks file hashes for locked dependencies  Automatically install required Pythons  if pyenv is available  Automatically finds your project home  recursively  by looking for a Pipfile  Automatically generates a Pipfile  if one doesn   t exist  Automatically creates a virtualenv in a standard location  Automatically adds removes packages to a Pipfile when they are un installed  Automatically loads  env files  if they exist    If you have worked on python projects before  you would realize these features make managing packages way easier    Other Commands   check checks for security vulnerabilities and asserts that PEP 508 requirements are being met by the current environment   which I think is a great feature especially after this - Malicious packages on PyPi  graph will show you a dependency graph  of your installed dependencies    You can read more about it here - Pipenv   Installation  You can find the installation documentation here  P S   If you liked working with the Python Package requests   you would be pleased to know that pipenv is by the same developer Kenneth Reitz

Recent progress  March 2014  Good news  Python 3 4 ships with Pip  Pip has long been Python s de-facto standard package manager  You can install a package like this   pip install httpie   Wahey  This is the best feature of any Python release  It makes the community s wealth of libraries accessible to everyone  Newbies are no longer excluded from using community libraries by the prohibitive difficulty of setup   However  there remains a number of outstanding frustrations with the Python packaging experience  Cumulatively  they make Python very unwelcoming for newbies  Also  the long history of neglect  ie  not shipping with a package manager for 14 years from Python 2 0 to Python 3 3  did damage to the community  I describe both below   Outstanding frustrations  It s important to understand that while experienced users are able to work around these frustrations  they are significant barriers to people new to Python  In fact  the difficulty and general user-unfriendliness is likely to deter many of them    PyPI website is counter-helpful  Every language with a package manager has an official  or quasi-official  repository for the community to download and publish packages  Python has the Python Package Index  PyPI   https   pypi python org pypi   Let s compare its pages with those of RubyGems and Npm  the Node package manager     https   rubygems org gems rails RubyGems page for the package rails  https   www npmjs org package express Npm page for the package express https   pypi python org pypi simplejson  PyPI page for the package simplejson   You ll see the RubyGems and Npm pages both begin with a one-line description of the package  then large friendly instructions how to install it   Meanwhile  woe to any hapless Python user who naively browses to PyPI  On https   pypi python org pypi simplejson    they ll find no such helpful instructions  There is however  a large green  Download  link  It s not unreasonable to follow it  Aha  they click  Their browser downloads a  tar gz file  Many Windows users can t even open it  but if they persevere they may eventually extract it  then run setup py and eventually with the help of Google setup py install  Some will give up and reinvent the wheel      Of course  all of this is wrong  The easiest way to install a package is with a Pip command  But PyPI didn t even mention Pip  Instead  it led them down an archaic and tedious path   Error  Unable to find vcvarsall bat  Numpy is one of Python s most popular libraries  Try to install it with Pip  you get this cryptic error message      Error  Unable to find vcvarsall bat   Trying to fix that is one of the most popular questions on Stack Overflow   error  Unable to find vcvarsall bat   Few people succeed   For comparison  in the same situation  Ruby prints this message  which explains what s going on and how to fix it      Please update your PATH to include build tools or download the DevKit from http   rubyinstaller org downloads and follow the instructions at http   github com oneclick rubyinstaller wiki Development-Kit   Publishing packages is hard  Ruby and Nodejs ship with full-featured package managers  Gem  since 2007  and Npm  since 2011   and have nurtured sharing communities centred around GitHub  Npm makes publishing packages as easy as installing them  it already has 64k packages  RubyGems lists 72k packages  The venerable Python package index lists only 41k   History  Flying in the face of its  batteries included  motto  Python shipped without a package manager until 2014    Until Pip  the de facto standard was a command  easy install  It was woefully inadequate  The was no command to uninstall packages   Pip was a massive improvement  It had most the features of Ruby s Gem  Unfortunately  Pip was--until recently--ironically difficult to install  In fact  the problem remains a top Python question on Stack Overflow   How do I install pip on Windows

As a Ruby and Perl developer and learning-Python guy  I haven t found easy install or pip to be the equivalent to RubyGems or CPAN    I tend to keep my development systems running the latest versions of modules as the developers update them  and freeze my production systems at set versions  Both RubyGems and CPAN make it easy to find modules by listing what s available  then install and later update them individually or in bulk if desired   easy install and pip make it easy to install a module ONCE I located it via a browser search or learned about it by some other means  but they won t tell me what is available  I can explicitly name the module to be updated  but the apps won t tell me what has been updated nor will they update everything in bulk if I want   So  the basic functionality is there in pip and easy install but there are features missing that I d like to see that would make them friendlier and easier to use and on par with CPAN and RubyGems
